DETACHABLE FASTENING FOQR VACClNATlON-S H |ELDS.

BPEGIFIQATION forming part of Letters Patent No. 702,741, dated JuneilY,1902. Application filed November 4,1901. Serial No. 80,998. (SpecimensJWakeman avenue, Newark, county of Essex,

State of New Jersey, have invented certain new and useful Improvementsin'Detachable Fastenings for Vaccination and Analogous Shields, fullydescribed and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to furnish an inherentlynon-corrosive means for securing a vaccination-shield in a detachablemanner, so that where adhesive straps are used to retain the shield inplace they need not be'disturloed when removing the shield to inspect ortreat-the sore.

The invention is practiced by providing the shield or straps with aninherently non-corrosive fastener bymea'nsof which the two can beengaged and disengaged at pleasure, and such anon-corrosive fastener isreadily made of aluminium, which is inherently noncorrosive.

In a copending application I have claimed an inherently non-corrosiveshield made of aluminium, and a metallic fastener of the desiredcharacter can beformed of tongues integral with such a shield andadapted to be bent over or under the straps to secure the shielddetachably thereto. I

In other cases a staple-shaped fastener may be adapted to embrace thestrap and project through holes in the shield, with the arms of suchfastener bent upon the outer side of the shield, or it may be made likea McGill paper- -fastener,with its tongues inserted through the strapand shield.

Non-corrosive material like the metal aluminium furnishes a fastenerwhich has no directly injurious efiect upon the skin and can be readilybent to engage or disengage the shield.

Several forms of the fastener are shown in the annexed drawings, inwh.ich

Figure 1 is a planof a shieldsecured to two straps by McGill fasteners;Figs2 is aside jected-from the outer sideof the strap. Fig. 5 is a planof a shield and straps secured thereto by staple-shaped fasteners. Fig.6 is a. cross-section of the strap and the shield ad- 'jacentto one ofthe fasteners shown in Fig. 5. Fig. 7 is a cross-section of one of thestraps with the arms of one of the fasteners projected from its outerside. Fig. 8 is a plan-of a shield having integral fasteners and tapessecuredthereby. Fig. 9 is a' cross-sectionof the tape and part ofthe'shield with the fastener formed as aprojeoting tongue, as shown uponthe left-hand end of the shield in Fig. 8. Fig. 10 is a cross-section ofthe tape and part of the shield with the fastener formedof two tonguesbent from slots in the shield, as shown upon the right-hand end of Fig.8. Fig. 11 is a-perspeotive-vie'w of part of the straps applied to awound,with fasteners projected outwardly from the straps, and a shieldindicated by dotted lines; and Fig. 12 is an end view of a shield with astud secured upon the same and the opposite ends of a strap buttonedupon such stud. I

a designates the flange of the shield, and b the convex portion toprotect the wound.

In Figs. 1 to 4: an aluminium fastener with two tongues o and a flathead d,.1ike aMcGill paper-fastener, is shown inserted through thestraps, with the tongues projected from the outer side. Figs. 1 to 3show the flange of the out-er side of two straps s and the tongues of vthe fasteners projected outwardly through the shield made with holese'and'applied to the Figs. 5 to 7, inclusive, show-fasteners of U shape'orstaple form havi'ng a tie-bar f and two arms g projected atright-angles therefrom. The two arms of. each fastener are shownembracing the strap and extended through two holes h in the flange oftheshield and bentdown upon the surface of the flange to lock the strapthereto. The arms of the stapleshaped fastener embrace or cross a partof the strap instead of penetrating a single point, like the fastenershown in Figs. 1 and 4, and the strap is thus held more securely, and Ihave therefore made a special claim to the shield having straps attachedby this form of fastening.

Fig. 8 shows tongues integral with the shield, which tongues can be usedas a fastener when the shield is made of inherently non-corrosive metal.In this figure a single lug 'i is shown projected from the left-hand endof such a shield and adapted to bend over or under the strap to lock thestrap thereto, Fig. 9 showing the strap on the under side of the shield.The flange is shown at the righthand side provided with two tongues j,punched from adjacent slots 7.: and adapted when projected at rightangles from the flange to embrace the tape like the arms of the stapleshown in Fig. 7 and to be bent down upon the tape, as shown in Fig. 10.WVith such tongues the shield can be applied to the outer side of thestraps if the case admits of the manipulation of the lugs upon the underside of the straps next to the skin; but if not the ends of the shieldmay be first fitted underneath the straps and the lugs then adjusted tothe straps and bent down upon the same.

Fig. 11 shows in perspective the surface S of a limb with a dottedshield over a cut indicated by dotted lines Z. The right-hand end ofthis figure shows an adhesive strap 5, having the McGill style offastener inserted through the same, with the head upon the under sidenext the skin and the tongues projected outwardly in readiness to securethe shield thereon.

The left-hand end of Fig. 11 shows near one end of the dotted shield astud m, adapted for insertion through the shield, and the opposite ends8 of a tape applied over the flange of the shield, as shown in Fig. 12,and formed with slits or buttonholes t to engage the stud.

All the means above described provide a non-corrosive fastener for theshield which permits its attachment by the ordinary strips of adhesiveplaster and permits the removal of the shield without loosening theplaster,

and thus avoids disturbing and irritating the wound or sore when it isnecessary to expose the latter.

By my invention when the adhesive straps have been once attached theshield can be re moved and replaced by manipulating the fastener whichconnects the shield to the strap, and the shield is thus secureddetachably by the straps already well known with the addition of thefastener, which by my invention is made wholly non-corrosive, andtherefore introduces no injurious element to the device. It is obviousthat the non-corrosive fasteners are adapted also for use with straps ofnonadhesive tape to prevent the irritation of the wound when removingthe shield.

What I claim as my invention is- 1. The combination, with a vaccinationor analogous shield having holes at opposite ends for the passage of afastener, of separate adhesive tapes having non-corrosive metallicfasteners with heads upon the adhesive sides of the tape and prongsprojected outwardly through the tape, and engaged with the holes at theopposite ends of the shield, whereby the shield can be repeatedlyengaged with and disengaged from the prongs without disturbing the tapeswhen once attached to the skin of the patient.

2. The combination,with an aluminium vaccination or analogous shieldhaving holes at opposite ends for the passage of a fastener, of separateadhesive tapes having non-corrosive metallic fasteners with heads uponthe adhesive sides of the tape and prongs projected outwardly throughthe tape and engaged with the holes at the opposite ends of the shield,whereby the shield can be repeatedly engaged with and disengaged fromthe prongs Without disturbing the tapes when once attached to the skinof the patient.

The combination, with avaccination or analogous shield, having holesnear its opposite edges to receivefasteners as set forth, of a pair ofstraps for securing the shield in place, and aluminium fasteners ofstaple shape having the barf crossing a partof the strap and their armsinserted through the holes in the shield and bent upon its surface,whereby the strap is securely held, and the part of the fastener uponthe adhesive side of the tapes in contact with the skin is ofnon-corrosive character.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
